Optical coherence tomography-verified morphological correlates of high-intensity coronary plaques on non-contrast T1-weighted magnetic resonance imaging in patients with stable coronary artery disease

Aims Coronary high-intensity plaques (HIPs) with a high plaque-to-myocardial signal intensity ratio (PMR) on non-contrast T1-weighted imaging in patients with stable coronary artery disease (CAD) are associated with future coronary events. To characterize the morphological substrate of HIP, we performed a correlative optical coherence tomography (OCT) study.
